CARBURETER.

' Specification of Letters Patent.

Patented Mar. 16, 1915.

Application led February 1, 1912. Serial No. 674,674.

To all whom it may concern 'ie it known that l, 'pulmones B. Einen, a citizen of the United States, and a resident ot' Asbury Park, in the county of Monmouth and State of New Jersey, have invented certain new and useful Improvements in Carbureters, of which the following is a specification.

The invention relates to improvements in carinii-eters for hydrocarbon engines, and it consists in the novel features, arrangements 2er dethe and combinations ofv parts hereina: scribed, and particularly pointed out in claims.

The object of my invention is to provide. a simple and highly ellicient carburetor for automatically supplying gas ot the requisite. quantity and quality to the cylinder of an engine, in accordance with the work tobe performed.

l contemplate the use of my carburetcr in connection with the cylinders ot' automobile engines 'for supplying gas thereto.

ythe carburetor of my invention comprises preferably a cylindrical casing affording a the air and gas to be connected by suitable piping with the engine cylinder, and a receptacle for the gasolene, said receptacle surrounding the mixing chamber and to be lauinectcd with a suitable tank or source of supply for the gasolene.

The receptacle containing the gasolene will be provided with a float for closing, when the desired quantity ot' gasolene has entered said receptacle, a valve controlling the inllov.' of gasolene from the tank or other source et supply to the receptacle, and said receptacle will be connected by a suitable tube or pipe and valve mechanism with the mixing chamber of the carbureter, said valve mechanism being adapted to permit` of' a variable discharge of the gasoliene in accordance with the requirements. and preferably being located at the pivotal axis of and discharging above a suitabley valve of the butterfly type employed for controlling the passage of air from the lower to the upper portion of said chamber. The mixing chamber is provided at its lower portion with a suitableair inlet and an automatic chec valve therefor. The buttertlv valve controlling the passage through the mii-ing chamber and the valve or control mechanism for securing the variable discharge of lrasolenc, are preferably connected together and operate synchronously to' admit proper proportions ot air and gasolene to said chamber above thc butterlly valve in accordance withtlie work required, whereby as the butterfly 0r air valve is turned to increase the opening through the mixing chamber, the sail valve mechanism will likewise open to a greater extent to supply the requisite quantity ol gasolene to the increased quantity of air then passing thrmigh the carburetor. l provide the butterfly vvalvc with a reasonably small opening extending through the same and equip said valve with a shutter by which this opening may be more or less opened or closed, thereby adapting the carbureter for the various conditions to be met in practice.

My invention results in the attainment of proper combustion, high efficiency in the engine and great economy in the consumption of the gasolcne, as well as accomplishingrl other important advantages. i

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the aeeompanying drawings, in which:

Figure l is a central vertical section through a carburetor embodying my invention. the section being on the dotted line 1--1 of Fig. (3; Fig. 2 is a side elevation of the carburetor, the view being taken Yfrom the right hand side of Figs. l and C; Fig. 3 is a horizontal section through the lower portion oli the. carbureter on the dotted line .Qi-3 of Fig. l; Fig. l is an enlarged vertical section through a portion of the mixing chamber and illustrates a portion ot the butterliy valve in edge elevation and the Valve mechanism for controlling the discharge of the gasolene above said valve in section:vr Fig. 5 is a transverse section through a portion of the butterfly valve and .the gasolenc discharge valve mechanism on the dotted line 5-5 of Fig. 4; Fig. 6 is a horizontal section through the carburetor on thc dotted line Gfti of Fig. 1; Fig. 7 is a vievv corresponding with Fig. 5, but showing a modification in the construction of the valve ucchanism for securing a variable discharge ot the'gasolene above tl;-` butterfly valve; Fig. 8 is a sectional view ol the same.

taken on the dotted line 8 8 of Fig. 7; Fig. l* is a view corresponding substantially with Figs. 4 and 7 and illustrating a further modied construction of gasolene discharge valve mechanism; Fig. 10 is a vertical section through the same, taken on the dotted line 10`10 of Fig. 9; Fig. 11 is section illustrating a further modification in the form of the discharge for the gasolene above the butterfly valve, and Fig. 12 is a section through the saine taken on the dotted line 12-12 of Fig. 11. v

In the drawings, rior cylindrical shell reter, 16 a top plate thereon, 17 a bottom plate or cap applied thereto, 18 a vertical tubular section concentric with and within the said exterior casingand forming within it the mixing chamber or conduit for the air and gas, and 19 a semi-circular float within the gasolenc receptacle 20 formed between the exterior' casing '15 and tubular section 18, said float being connected toa plate 21, which is pivotally secured at 22 within a passage 23 leading from a gasolene receptacle 24, which may be integral with the casing 15. The gasolcne for the supply of the carbureter enters the receptacle 24 through an inlet 25 controllable by a valve 26 in a well known manner. I make no specific claim for the receptacle 24, since it furnishes merely the intermediate chamber through which the gasolene flows to the main gasolenc receptacle 20. rlhe movement of the lioat 19 operates through the pivoted plate 21, as the gasolene 'lowers in the receptacle 20,` to open the valve 26, so that an additionalsupply of the gasolene may flow into the receptacle 20. lVhen the float 19 is elevated by an admission of a proper quantity of gasolene to the receptacle 20, it acts to turn the outer end of the plate 21 downwardly within the receptacle 24 and permits or eiliects the seating of the valve 2G and the cutting off of any further supply of gasolene through the inlet 25.

The outlet for gasolene from the receptacle 20 to the mixihg chamber in the casing 18 is through a tube 27 communicating with the receptacle 2O andcxtending transversely inwardly into said\- mixing chamber, and a valve mechanism located at the inner end ofsaid tubing 27 and, in the construction shown in Figs. 1, 1 and 5, comprising a rstationary hub 28 on the inner end of said tube 27 and a rotary cap 29 fitting upon said hub and connected with the shaft 30 which carries the butterfly valve 31. The tube 27 has in the side of its inner end a slot 32, and this slot is in line with a dovetailshaped slot. 33 in the hub 28, as shown more clearly in Fig. 5. The cap 29 is provided with a slot 34 which on the rotation of said cap with the butterfly valv'e 31 Aenters more or less into register with the slot 33 in the hub 28,

15 designates the exte. or casing of the carbu tlie gasolene in .ter or ids ance with the work required the butterfly valve 31is, after the engine has been started, turned to carry an increased extent of the slot 31 into register admit an increased supply of air up into the mixing chamber 18. The slot 34 is in its movement timed with the movement of the butterfly valve 31, and hence as the valve 1 is turned to admit a greater or less quanwith the slot 33 and` tity of air to the mixing chamber, the slot 34 is likewise moved to expose a greater or less .extent of the slot 33 and the gasolene therein to the suction action of the engine. The discharge of the gasolene is at the upper side of the valve 31 and at the upper portion of the mixing chamber 18. i l.

Vithin the tube 27 I preferably provide an adjustable disk valve 35, the same being secured on the inner end of a rod 36 extending through a threaded opening in a bear ing at the outer end of the tube 27 and provided with a crank member 37 by which the rod may be conveniently rotated. The disk. 35 is at the extreme inner end of the tube 27 and its purpose is to enable the adjustment of the slot 32 in said tube with respect to the extent thereof which shall be exposed. If, looking at Fig. 4, the rod 36 is turned to draw the valve disk 35 toward the left, said disk will partly close the slot 32 and to that extent restrict the opening through which the gasolene may escape to the mixing chamber. The disk valve 35 is desirable in that it enables the adjustment of the carburetcr to the wants of the particular engine to whichit may be applied.

I do not wish to limit my invention to the identical valve mechanism illustrated in Figs. 1, 4 and 5 for controlling the discharge of the gasolene, since I am aware that said valve mechanism may be modified in many ways in accomplishing the purposes of my invention. I have, therefore, illustrated in Figs. 7 to 12 inclusive several modified constructions of the gasolene discharge feature, all of them providing for the discharge of the gasolene above the butterfly yalve and in theupper portion of the mixing chamber,

The constructions shown in Figs. 7 lto 12 inelusive do not modify the construction of the tubular section 1S allordmg the mixing ltube The tubular portion of the ber, and said tube 38 has formed in its side near its inner end a slot 39 and preferably will contain a disk valve corresponding with the valve shown in Fig. 4. The rotary slieft carrying the butterfly valve l numher 40.; and this shaft is inade tubular at its inner ond to slip over and rotate upon1 thfe s ia t 40 is provided with a slot il, which is in the soin vertical. plane with the slot 39 in Y t and on the rotation of the shall l it more or less into register Wiih,

The Construction shown in Figs. ti and lll, While a modification of the construetion of Fig. Si, has a siniilai operation to that thereof. in Figs ll and '12 I number the inlet tube ,for gasolene 50and this tube will reierably contain a disk valve correspon ing with the disk i o shown in Fig, 4 and have in the side ov its inner end a slot 51 for the escape of the gasolene. 'l he rotary shaft 52 carrying the butterfly valve, which l number 53 in this modification, has at its inner end a cap 54 fitting upon the inner end of the stationary tube 50. In the use of the construction shown in Figs. ll and 12 I may adjust the size of the opening 51 by means of the 'disk-i aire in the tube 50, and thereafter said opening will remain uncovered, since the cap 54 does not extend over said opening 51. The opening 5l is, however, above the butterfly valve and in the upper portion of the mixiiig'chamber.

to the vehicle, this being a feature of advantage.

The operation of the carbureter Will be understood from the foregoing description without further extended detailed explanation.

The carbureter having been applied in position and the receptacle 20 having been supplied with gasolene, the operation of the air or butterfly valve 31 and the gasolene discharge valvc mechanism above said butterHy valve will, with the exception of the construction shown in Fig 11, be under the direct control of the on the cal through the medium of a connecting rod 57, crankarm 5S and shaft 30, this shaft carrying the butterliy valve and me member of said gasolene discharge vave mechanism. The suction stroke the piston of the engine will be dcpemled on, in the form of my invention illustrated, valve 69. The driver wi ll open the butterfly valve 31 and the valve mechanism control` ling the discharge of gasolene to a greater or less extent, the requirements of the engine may demand.

t `,is one of the important features of the invention that the driver may regulate the quantity of gasolene that shall escape to the mixing chamber and that at the same time he may control by the position of the valve 31 the quantity of air in said chamber to mix with the gasolene. The operation of he valve 31 and the gasolene discharge valve mechanism, in its.several forms shown, Will be readily understood from the descri tion hereinbefore given. In respect to tlie construction shown in Figs. 11 and 12. the outlet 51 for gasolene, while capable of being adjusted as to size, has no other control features connected with it, and in that respect it differs from the valve constructions shown in the other figures of the drawing. In the construction shown i Fig. ll the butterfly valve is carried by the shaft 52 and the discharge 51 for said valve and in the upper portion of the gasolene is abov'e mixing chamber, provement over comprising a casing, a mixing-chamber for the air and gasolene or the like, a rotary butterfly valve within and controlling the passage through said chamber and having an opening and an adjustable damper for said opening, and a valve mechanism Within said chamber for ga ging members having a "ariable outlet f mixing-chamber for the air and gasolene or the like, a rotary butterfly valve within and controlling the passage through said chamber, and a valve -mechanism Within said chamber for controlling the escape of the gasolene, said valve mechanism comprising cooperative engaging members having a. variable discharge outlet for gasolene and being connected with valve lation to the other member and the size of said outlet in accordance with the position of said valve.
